7-300 Norma Mag Improved. IT’S ALIVE!!

Thx for the clarification.

I've run a 7 Mashburn Super for 3 decades and a few..barrels. Love the Big 7's!

It's not the beast that you're NMI is (I used to dream about doing a #1 in 7/378Wby) I suspect that you're getting another 150 fps over what I do.

However my barrel life is up in the 2500 rounds range:)
 
100 pieces of formed and prepped 7-300 NMI brass. Ready for the season now 🙌🏼🙌🏼

Now all you need is a boat load of time, gas for your truck and of course a few tags...need me to print you some:)
 
Just realized I was out shooting my buddy's 28 Nosler, right along side the 7-300 NMI with the same bullet side by side for a direct comparison.

7-300 NMI. 23.5" barrel
180 ELDM
83gr. H1000
CCI 250
3100fps

28 Nosler. 24" barrel
180 ELDM
83gr. N570
CCI 250
3040fps
How much more speed would you get with N570 ? Maybe another 70-100 fps ?
 
Can you say record turn around?? lol.

Dropped off the new barrel to @Barehandlineman11 on Friday night. And got a brand new gun by Sunday night??? EPIC

End up finishing it at 26" instead of 24" because I had .760 OD muzzle brakes and that's where they matched the contour perfectly. A little extra speed never hurt anyone lol.

This is a 1-9 twist #6 contour brux, with the shank shortened slightly. This SHOULD be the barrel I hunt with this season 😅😅, so he went ahead and cerakoted this one haha.
